YEEEEAAHHHHH
Honestly, if it's tasteful, and it makes "some" sense, I see nothing wrong with it. I mean, the guy I know with all the STI goodies buys them because most, as with the lights, muffler, water sprayer, scoop, and intercooler simply work better than the OE peices. Additionally, most parts were sourced through our own circle of friends from a guy who had an STI with a front-mount and an aftermarket exhaust. Sure, it'd kinda ricy to put an STI wing on a non-STI, but who cares? As long as you don't brag about it, and it looks good - get on with it.
